FAQs

1. What is the maximum sample volume that can be processed in the centrifuge?

The maximum sample volume depends on the type of rotor used with the centrifuge. Typical rotors can accommodate sample volumes ranging from 0.2 mL (microcentrifuge tubes) to 50 mL (conical tubes) or larger for specialized rotors. It is important to check the centrifuge's specifications and rotor compatibility to ensure that the sample volume does not exceed the recommended limits, which could affect centrifugation efficiency and safety.

2. How to balance the centrifuge before operation?

Proper balancing is critical for safe and effective centrifuge operation: 1) Ensure that all sample tubes have the same volume and weight; 2) Place the tubes symmetrically in the rotor, opposite each other; 3) For odd numbers of samples, use a balance tube filled with the same volume of appropriate solution; 4) Check that the rotor is properly seated and secured in the centrifuge; 5) Avoid overloading the rotor beyond its maximum capacity.

3. What is the difference between relative centrifugal force (RCF) and revolutions per minute (RPM)?

RCF is a measure of the centrifugal force applied to the sample, expressed in multiples of gravity (x g), and depends on both the RPM and the radius of the rotor. RPM is a measure of the rotor's rotation speed in revolutions per minute. The relationship between RCF and RPM is given by the formula: RCF = 1.118 × 10^-5 × r × RPM² (where r is the rotor radius in centimeters). For most applications, RCF is the preferred parameter as it directly relates to the separation efficiency, regardless of rotor size.

4. How to maintain the centrifuge to ensure long service life?

Regular maintenance includes: 1) Cleaning the rotor and chamber after each use to remove sample spills and debris; 2) Inspecting the rotor for cracks, corrosion, or wear before each use; 3) Lubricating moving parts according to the manufacturer's recommendations; 4) Calibrating the speed and temperature controls annually or after major service; 5) Ensuring proper ventilation around the centrifuge to prevent overheating; 6) Storing the centrifuge in a clean, dry environment when not in use.

5. What safety precautions should be taken when using the centrifuge?

Important safety precautions include: 1) Always balance the sample tubes properly before operation; 2) Ensure the rotor is correctly installed and secured; 3) Do not open the centrifuge lid while the rotor is still spinning; 4) Use appropriate personal protective equipment (gloves, goggles) when handling samples and cleaning the equipment; 5) Avoid overloading the centrifuge beyond its maximum capacity; 6) Regularly inspect the centrifuge for any signs of damage or malfunction and discontinue use if any issues are found.
